+The Postfix default configuration can easily be extended by providing a `config/postfix-main.cf` in postfix format.
+This can also be used to add configuration that is not in our default configuration.
+
+For example, one common use of this file is for increasing the default maximum message size:
+```
+# increase maximum message size
+   message_size_limit = 52428800
+```
+
+[Postfix documentation](http://www.postfix.org/documentation.html) remains the best place to find configuration options.
+
+Each line in the provided file will be loaded into postfix.
+
+Have a look at the code for more information.
